For years, one question has shadowed the ambitions of every institution considering tokenised securities on a public blockchain: what happens to our positions, our counterparty details, our transaction history? If any node on the network can read the data, the case for moving regulated assets onchain becomes structurally difficult. Yesterday, Polymath published what may be the most direct answer yet to that question.

For years, one question has shadowed the ambitions of every institution considering tokenised securities on a public blockchain: what happens to our positions, our counterparty details, our transaction history?


If any node on the network can read the data, the case for moving regulated assets onchain becomes structurally difficult. Yesterday, Polymath published what may be the most direct answer yet to that question.


Polymath, the regulated asset infrastructure company behind the Polymesh blockchain, announced the launch of Confidential Assets on 27 May 2026. The feature is a native, protocol-layer privacy mechanism that allows financial institutions to transact tokenised securities and real-world assets on a public blockchain while keeping positions, balances and counterparty details fully private. It does this using zero-knowledge cryptography, shielding transaction details from public view while preserving the ability of regulators, auditors and authorised parties to access the information they are entitled to see.


The significance of this is difficult to overstate for anyone who has followed the conversation around institutional tokenisation. The dilemma has always been a genuine one. Public blockchains offer the open settlement rails, composability and interoperability that make tokenised assets genuinely useful. Private or permissioned chains offer confidentiality, but at the cost of the network effects and liquidity that matter most to institutional market participants. Confidential Assets is designed to collapse that trade-off.


What it does, precisely

Confidential Assets operates at the protocol level on Polymesh, which was purpose-built for regulated securities rather than retrofitted from a general-purpose blockchain. This matters because privacy that is bolted on as an application layer tends to be fragile, limited in scope, or both. By integrating zero-knowledge proofs natively, Polymath ensures that confidentiality applies to the full lifecycle of an asset, including issuance, transfer, settlement and corporate actions, not just to individual transaction legs.


For institutions, the practical effect is that a fund manager tokenising a private credit instrument on Polymesh can transact with counterparties on the same network without exposing its portfolio composition to competitors, or disclosing commercially sensitive position data to anyone other than explicitly authorised parties. Regulators and auditors retain full visibility through permissioned access channels, preserving the compliance function that makes institutional tokenisation commercially viable.


Polymath describes Confidential Assets as addressing one of the most persistent barriers to institutional adoption of tokenised finance, and it is hard to disagree. Every major bank and asset manager that has explored tokenisation at scale has cited data confidentiality as a central concern. That concern has driven many towards permissioned architectures, which in turn has fragmented the market into a collection of siloed networks with limited interoperability.


The UK and European angle

For UK and European market participants, the relevance is immediate. The FCA and Bank of England published their joint call for input on the future of tokenisation for UK wholesale financial markets in May 2026, with responses due by 3 July. A core theme in that paper is the infrastructure question: what kind of blockchain architecture can support the compliance and privacy requirements of regulated financial markets while enabling the efficiency gains that make tokenisation worth doing?


Polymath's Confidential Assets does not answer that question for regulators, but it does change the terms of the debate. The argument that public blockchains are inherently incompatible with financial privacy is now harder to sustain. Institutions and their advisers evaluating responses to the FCA and BoE consultation now have a concrete, live example of protocol-level privacy on a purpose-built regulated blockchain to point to.

For founders building on tokenisation infrastructure, the launch is equally relevant. Platforms that want to offer tokenised equity, tokenised fund units or tokenised private credit to institutional investors need to be able to guarantee confidentiality to those investors.


If the underlying blockchain can do that natively, the compliance case for institutional adoption becomes structurally stronger.


Key Takeaways

  • Polymath launched Confidential Assets on its Polymesh blockchain on 27 May 2026, using zero-knowledge cryptography to shield transaction details on a public blockchain while preserving regulatory access.

  • The feature operates at the protocol level, meaning confidentiality applies across the full asset lifecycle rather than being an application-layer add-on.

  • The launch directly addresses one of the most commonly cited barriers to institutional tokenisation: the incompatibility between public blockchain transparency and the privacy requirements of regulated financial markets.

  • UK and European institutions evaluating their tokenisation infrastructure in light of the FCA and BoE joint consultation have a live, purpose-built example of public-chain privacy to consider.

  • Polymath's Polymesh blockchain was purpose-built for regulated securities, giving it structural advantages over general-purpose chains that have retrofitted privacy features.
